An investigation to determine the effect of short-term low-dye taping on vertical ground reaction forces in asymptomatic PES planus, cavus and normal feet

Abstract

Low -Dye taping is a method commonly used in sport participation and normal daily activity (Harradine, Herrington and Wright, 2001). It has been indicated in support of injured structures, decreasing edema and protection against re-injury (Reid, 1992:232). Contrary to these beliefs, studies have shown that low -dye anti-pronatory control is lost after relatively short episodes of exercise (Ator et al., 1991 and Vicenzino et aL, 1997). The variations in dynamic foot function with low -dye taping is not well understood, although tapin.g of the foot in low-dye type method has been advocated by many authors (Brantingham et aL, 1992, Ryan, 1995 and Chandler and Kibler, 1993). It was the purpose of this study to investigate the maximum ground reaction force and percentage contact time within 10 demarcated regions of the foot in asymptomatic patient with pes planus, cavus and normal medial longitudinal arches at four time intervals over 24 hours. Having established its baseline function it may serve as point of reference for clinical trials that wish to determine the role of taping as part of the management of symptomatic feet. This trial consisted of 60 participants with asymptomatic feet that were divided into three groups of 20. Participants were divided into three groups depending on their respective foot structures. To qualify for one of the three groups subjects had to either have flexible low, high or normal medial longitudinal arches. Maximum ground reaction forces (GRF) and Percent contact time was obtained for each of the three groups and for each of four visits. GRF were obtained with the aid of a registered orthotist who has agreed to work with the researcher on this project using the RSscan International 1m footscan plate system (Appendix L). The data was interpreted and analyzed using the RSscan Clinical Version 7.08 software package.
